The packet encryption algorithm divides the data into fixed-length packet processing, and the input length of the algorithm is a grouping length. In order to improve the security and adapt to different application environments, packet encryption has many different working modes. The four most common modes of operation are: ECB,CBC,CFB,OFB.ECB mode,The ECB mode is the simplest basic mode. Under the control of the key, the input of a packet length is converted to the output of a packet length. A p

1) Encryption suite interaction;2) password Exchange;3) identity authentication;Full handshakeInitially, client and server "agree upon" null encryption with no MAC and null compression. This means the record they would first send would be sent as cleartext and unprotected.First message of a handshake is a ClientHello . It is the message by which the client states its intention to do some SSL. Note that the "client" is a symbolic role; It means "the party which speaks first". It so happens this i

Reprint Address: Java version AES encryption algorithm The Advanced Encryption Standard in cryptography (Advanced encryption Standard,aes), also known as Rijndael encryption, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After five years of selection process, the Advanced Encryption Standard was issued by the National Institute of Standards and Technology (NIST) on November 26, 2001

Among them, the Key is a 7-byte 56-bit, which is the working Key of the DES algorithm; the Data is 8-byte 64-bit, which is the Data to be encrypted or decrypted; the Mode is DES, which can be encrypted or decrypted.
